T-Mobile is trying something new: an early upgrade plan that lets users trade in their smartphones for a newer model up to three times a year. The initiative, called JUMP! On Demand, leases out phones rather than selling them, and is aimed at tech junkies itching to upgrade their phones more often than they already do.

Customers are locked into an 18-month leasing contract for JUMP! On Demand, though they have the option of purchasing the phone at the end of that time frame. T-Mobile is promoting the launch with an offer for an iPhone 6 at a rate of $15 a month. The mobile company’s previous JUMP! upgrade program, which launched in 2013, will continue to be available to consumers.
